Preparation of Decellularized Rat Kidney: A Procedure to Generate Acellular Vascularized Whole-organ Scaffold from a Harvested Rat Kidney

Abstract

Source: Kim, E. H. et al. Preparation of Decellularized Kidney Scaffolds in Rats. J. Vis. Exp. (2021)

This video describes the preparation of a decellularized rat kidney. The obtained acellular vascular scaffold can serve as a promising platform for tissue engineering of organ grafts.

Protocol

All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board.

1. Kidney Harvesting and Decellularization

1. Harvest the left kidney with the abdominal aorta and inferior vena cava.
2. Ligate the ureter, thoracic aorta, superior vena cava, and branches of the abdominal aorta.
3. Keep the organ hydrated in Dulbecco's PBS (DPBS) in a 10 cm Petri dish.
4. Cannulate the abdominal aorta and inferior vena cava with a 23G catheter. To remove residual blood, connect the cannula with a peristaltic pump and wash with DPBS (....
